I added the iconbutton in the customlistview successfully. but in the button_click() event I couldn't use customlistview.getItemFromView(sender) because iconbutton is not a view while getItemFromView(view as View) expects
view argument.
As I have not access to original library I am not able to use reflection library also. Would you help me to use iconbutton for this purpose.

best Regard

I searched github with iconbutton library name. It seems there is not a function to cast iconbutton as view there.
If you are able to solve this problem the library will be more complete.
thanks

Try the version attached (also new in Post #1)

and get inspired here

B4X: 
Sub IconButton_Click()
    Log("Button click")
    Dim ib As IconButton = Sender
    Log(ib.Tag)   
End Sub

new version added to customlistview panel , but unfortunately is invisible in android 5 while button event get done . I tested on android 4.2.2 that showed correctly.
Also I added webview to viewpager panel that showed correctly on android 4.2 but blank on android 5
I don't know this relates to iconbutton and webview or something else.

Just I was in doubt which library causes the blank webview and missed iconbutton so I posted in both places
I will try the updated AHViewPager library which is designSupport. Am I in the right track ?

Not really, just downloaded, there is still no icons :)
Click to expand...
I just did a download of the example from post #1. The icons ARE in the files folder

incendio said:
Any chance set icon possition on top or bottom ?
Click to expand...
The underlying Library does not expos a method to change the position to top or bottom.

Thanks for this lib, its very usefull. But I'm having a small problem. I used your example and created events just for the first button ib1
B4X: 
Sub ib1_Down()
    Log("down")
End Sub

Sub ib1_Up()
    Log("up")
End Sub

Sub ib1_HoverEnter()
    Log("hover enter")
End Sub

Sub ib1_HoverExit()
    Log("hover exit")
End Sub

Then when I push the ib1, without releasing the finger from it, the code goes through all four events I created: Down, Up HoverEnter, HoverExit.
What am I doing wrong?
thank you for your help

You can see the attached example.

Maybe...
what I would like to achieve is to have buttons changing color when pushed. I used the way shown on this example with normal views, but here, when the first button is pushed, the code executes the _Up() sub also. Any idea? thank you

Is there a way to set the font-size on an iconbutton in code?
It can be set in the designer, but there is not method for text-size...that I can find.
Thanks,
Rusty
